*varargs.h - XENIX style macros for variable argument functions
|
|
*
|
|
* Copyright (c) 1985-2001, Microsoft Corporation. All rights reserved.
|
|
*
|
|
*Purpose:
|
|
* This file defines XENIX style macros for accessing arguments of a
|
|
* function which takes a variable number of arguments.
|
|
* [System V]
|
|
*
|
|
* [Public]
|
|
*
|
|
*Revision History:
|
|
* 08-22-88 GJF Modified to also work for the 386 (small model only)
|
|
* 05-03-89 JCR Added _INTERNAL_IFSTRIP for relinc usage
|
|
* 08-15-89 GJF Cleanup, now specific to OS/2 2.0 (i.e., 386 flat model)
|
|
* 10-30-89 GJF Fixed copyright
|
|
* 11-02-89 JCR Changed "DLL" to "_DLL"
|
|
* 01-05-90 JCR Added NULL definition
|
|
* 03-02-90 GJF Added #ifndef _INC_VARARGS stuff. Also, removed some
|
|
* (now) useless preprocessor directives.
|
|
* 05-29-90 GJF Replaced sizeof() with _INTSIZEOF() and revised the
|
|
* va_arg() macro (fixes PTM 60)
|
|
* 05-31-90 GJF Revised va_end() macro (propagated 5-25-90 change to
|
|
* crt7 version by WAJ)
|
|
* 01-24-91 JCR Generate an error on ANSI compilations
|
|
* 08-20-91 JCR C++ and ANSI naming
|
|
* 11-01-91 GDP MIPS Compiler support
|
|
* 10-16-92 SKS Replaced "#ifdef i386" with "#ifdef _M_IX86".
|
|
* 11-03-92 GJF Fixed several conditionals, dropped _DOSX32_ support.
|
|
* 01-09-93 SRW Remove usage of MIPS and ALPHA to conform to ANSI
|
|
* Use _MIPS_ and _ALPHA_ instead.
|
|
* 10-04-93 SRW Fix ifdefs for MIPS and ALPHA to only check for _M_?????? defines
|
|
* 10-13-93 GJF Merged NT and Cuda versions.
|
|
* 04-05-94 SKS Add prototype of __builtin_va_start for ALPHA
|
|
* 10-02-94 BWT PPC merge
|
|
* 11-03-94 GJF Ensure 8 byte alignment.
|
|
* 02-11-95 CFW Add _CRTBLD to avoid users getting wrong headers.
|
|
* 02-14-95 CFW Clean up Mac merge.
|
|
* 12-14-95 JWM Add "#pragma once".
|
|
* 02-24-97 GJF Detab-ed.
|
|
* 10-07-97 RDL Added IA64.
|
|
* 11-07-97 RDL Soft23 varargs.
|
|
* 05-17-99 PML Remove all Macintosh support.
|
|
* 10-25-99 PML Fix IA64 _APALIGN macro (VS7#51838).
|
|
* 10-25-99 PML Add support for _M_CEE (VS7#54572).
|
|
* 01-20-00 PML Remove __epcg__.
|
|
* 03-26-01 GB Added va_args for AMD64
|
|
* 05-17-00 PML Use __alignof in _APALIGN macro for IA64.
|
|
* 03-26-01 GB Added va_args for AMD64
|
|
* 07-15-01 PML Remove all ALPHA, MIPS, and PPC code
